PENCILHSHARPENER.

IFATIN forming part of Letters Patent No. 350,930, dated @ctcber 19, 1886,

Application filed October 24, 1F85.

To all ZULONL il? 77mg/ concern:

Be it known that I, JOHN M. GniFrrrH, a citizen ofthe United States, residing at Philadelphia, in the-county of Philadelphia and State ot' Pennsylvania, have invented certain new and useful Improvements in Pencil-SharpA eners, of whiehthet'ollowing is a specification, reference being had to the accompanying drawings.

This invention has relation to pencil-sharpeners; and it consists in certain features of construction hereinafter described, and particularly pointed out in the claim.

Referring to the drawings, Figure lV is a plan, and Figs. 2 and 3 are sections on the lines l 2, 3 4, in Fig. l, respectively, ol' a pencil-Sharpener constructed in accordance with my invention.

Like letters indicate like parts in all the figures.

A represents the sharpener proper, which consists ofa plate of steel cut and cross-cut like a tile to produce teeth or an abradingsurface, the cuts being made diagonally and transversely to the length of the plate and at right angles to each other.

An aperture, B', in the handle B is convenient for suspending the sharpener.

As illustrated in Figs. il, 2, and 3, the handle B is made of sheet metal, which is corru gated, as at B2 B", and provided with rounded edges B, all of which serve to not only ornament the handle, but also to give additional strength thereto. A recess, B", is reamed for the reception of the plate A, the walls or flanges B6 serving, either with or without suitable cement, the purpose of retaining the plate within the handle.

The general object of the invention is to provide a pencilsharpener for the use of school children which shall be compact, simple in construction, capable of being produced at the slightest possible expense, and one which can be used in sharpening either lead or slate pencils without soiling the hands, as either the Sharpener may be held stationary Serial No. 130809. (No model.)

by one hand by the handle B and the pencil reeiprocated and rolled thereon, or the pencil may be held and rolled in one hand while the Sharpener is reeiproeated thereon by the other.

I'Ieretofore, when pencil-Sharpeners have been made of toothed steel plates, special shapes thereof have been required to form handle portions and suspension devices both for the article itself and for slates to which said articles have been attached. Such constructions necessitate the special provision of portions of the steel which is not toothed. Pencil-.Sharpeners have also been heretofore made of glass with integral handles or set in handles of cast-brass. By my improvement along bar of steel provided with an abrading-surface can be readily broken up into short pieces, which, by reason of its being brittle, are smooth enough at the ends without further cutting ortiuishing. For a handleIutilize new scrap tin or other sheet metal, very small pieces otherwise wasted being sufficient, from which, by suitable dies, I cut out and simultaneously strike up a neat, strong handle having flanges which are bent over the unnished edges of the steel Sharpener, so that a finished serviceable implement is produced at a very slight cost-an essential requirement of articles of this class.

Having described my invention, what I claim is- As an article of manufacture, a pencilsharpener consisting of a rectangular piece ot' steel with broken unfinished ends, corrugated upon one surface, and embedded in and having its ends and side edges covered by the ilanges Bi ofan integral sheet-metal backing and handle having strengthening corrugations B2 B3 and rounded edges B, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
